Joseph Haydn's Piano Trio No. 45 in E♭ major, Hob. XV:29, was published in 1797 but may have been written a few years earlier, while Haydn was still in England on the second of his highly successful London visits. It is the third piano trio of a set of three dedicated to the eminent pianist Therese Jansen Bartolozzi. It is the least technically sophisticated of the three in a set noted in general for their wide expressive range and virtuosity—piano trios at this time were typically written with amateur performers in mind. But it is still full of character and humour.
